SPE does not look like much faster than C,why?
this is my code with C and SPE.
/******code with C*******/
/******code with SPE*******/
Hello,
As reference manual express:
SPE accelerates operations via the use of short vectors (two, four, or eight elements) within 64-bit
GPRs and the use of Single Instruction Multiple Data (SIMD) operations. SPE 2.1 also includes an accumulator register to allow
for certain back-to-back operations without loop unrolling.
Best regards,
Peter
